Muhammad Ali blew away Brian London to retain the WBC heavyweight title, the Ring magazine belt and lineal heavyweight championship on August 6 in 1966.

It was a total disaster for the British bulldog at the Earls Court Arena in London as 'The Greatest' gave him a hiding in the third round.

A big right hand sent London stumbling backwards, after a hellish two rounds previously, and Ali unloaded a furious barrage of strikes to take his man out of there.

Ali bounced around on his feet in the first round with his hands hanging loosely by his sides in an obvious attempt to bait London into leaving himself open for a counter attack.

The 6ft 3in American appeared to tower over the Lancaster bomber whose shaky legs seemed to betray his confidence right from the start.

Ali enjoyed a bright start to the fight but he was briefly caught off guard by London with a left jab who failed to capitalise on the early opening.

After that it was only downhill from there on in as Ali began to take control after taking a few moments to recover from his lapse in concentration.

London was ultimately made to pay for his tentative approach in the third round as Ali stung him with a right hand and his legs stiffened.

He backed up against the ropes as he tried to gather his wits about him but that ultimately proved to be his downfall as the end came a few moments later.

Another big right hand robbed London of all his senses and he looked like he didn't want to be in there.

Unable to defend himself, he stumbled backwards before being battered to the floor and could not beat the count.

On Saturday, user @b0xingfan shared the footage on Twitter to remind boxing fans the fight happened exactly 56 years ago to the day.

London, who died last year at the age of 87, later admitted that he knew he had no right being in there with Ali but needed the money to support his family.

He told Boxing News in 2016: "He was far too good for me. He was a brilliant fighter and I wasn't good enough to fight him.

"When they offered me the money to fight him I just said 'yes' and I thought that I'd go for it but I knew I had no chance.

"My problem was I never really fought for the love of it - I fought for the money."
